KILZ Basement and Masonry Waterproofing Paint
This premium interior/exterior paint is formulated to waterproof and seal porous concrete and masonry surfaces both inside and outside a home. Using nanotechnology, the coating forms a barrier to help stop water infiltration while an alkali-resistant finish provides long-lasting durability and a decorative look. It’s suited for properly prepped and cured above and below grade basement walls, masonry walls, retaining walls, cinder and concrete blocks, stucco, and brick. It should not be used on floors or on walls with active water leaks. Application options include a high-quality 1/2″-3/4″ nap roller, 4″ nylon/polyester brush, or an airless sprayer delivering 2200-3200 PSI with a .023″-.025″ spray tip.
KILZ Self-Priming Masonry, Stucco and Brick Paint (Gray)
This high-quality acrylic latex water-base interior/exterior paint offers excellent hiding properties with strong adhesion and water repellency on textured interior and exterior surfaces. It self-priming, delivering good coverage on smooth, rough, and textured masonry, drywall, stucco, and brick. The formula is alkali-resistant up to pH 12.0, easy to apply, and cleans up with soap and water. It can be rolled, brushed, or sprayed for versatility in application across various surface profiles.
INSL-X WaterBlock Acrylic Masonry Waterproofer
WaterBlock is a water-based coating designed to seal vertical interior and exterior concrete walls, including basement walls, foundations, retaining walls, cinder blocks, stucco, and brick. It dries quickly to form a waterproof barrier and features high alkali resistance, up to pH 13. This product provides a durable finish that helps protect against moisture intrusion and salt efflorescence while maintaining compatibility with various masonry substrates.
KILZ Self-Priming Masonry, Stucco and Brick Paint (White)
This self-priming acrylic latex water-base interior/exterior paint offers excellent hiding properties with strong adhesion and water repellency on textured surfaces. It provides a durable finish on smooth, rough, and textured masonry, drywall, stucco, and brick. Alkali resistance up to pH 12.0 is a key feature, and like the gray variant, it is easy to apply and cleans up with soap and water. It can be rolled, brushed, or sprayed, giving users flexibility for project scale and surface type.
Rustins Masonry Paint White 250ml
Rustins Masonry Paint in White comes in a compact 250ml can, suitable for small projects or touch-ups on masonry surfaces. The product requires a clean, dry surface free from dust and contaminants to ensure adhesion. It offers a straightforward application with a large brush for even coverage and is best used on properly prepared substrates to maximize durability and appearance on concrete, brick, or stucco surfaces.
Buying Guide: Key Purchase Considerations
- Surface type and location: Exterior walls, basements, foundations, or interior rooms require different bonding and waterproofing properties. Choose a product designed for the specific exposure (above/below grade, moisture-prone areas).
- Waterproofing vs. water resistance: If moisture intrusion is a primary concern, prioritize waterproofing coatings with barriers and alkali resistance. For decorative finishes with some moisture tolerance, select a high-adhesion paint with water repellency.
- Primer requirements: Some products are self-priming, reducing steps and time. Others may require a separate primer for best adhesion on challenging substrates like rough masonry or damp surfaces.
- Finish and appearance: Consider finish type (matte, satin, flat) based on appearance and maintenance needs. Lighter colors can help reflect heat, but darker tones may show imperfections more readily on rough surfaces.
- Application method: Options include rolling, brushing, or spraying. High PSI sprayers and appropriate spray tips enable even coverage on large areas or rough textures.
- Alkali resistance: Concrete and masonry surfaces often contain high alkalinity. Choose products with alkali resistance (pH 12-13) to prevent paint deterioration and delamination over time.
- Size and coverage: For larger basements or exterior walls, select gallon-sized containers or multiple units to ensure color consistency and sufficient coverage. For small repairs, 250ml or 500ml options can be convenient.
- Maintenance and cleaning: Water-based coatings clean up with soap and water, which simplifies post-application maintenance and touch-ups.
All products listed here are designed to address common concrete and masonry challenges, including water exposure, efflorescence, and adhesion on porous surfaces. When selecting a coating, verify surface prep requirements such as cleaning, drying times, and any needed sealing steps. Proper surface preparation will maximize durability and the protective performance of the chosen masonry paint.
